The multimedia-rich EliteOne G1 systems, which are being embraced in health-care and education markets, also feature HD Webcam, DTS studio sound and a 23-inch height-adjustable diagonal display with VESA mounting options.

The EliteOne G1 800 systems also feature an option that allows the systems to share an Internet connection, with up to five additional devices, via a wireless hotspot application that requires a separately purchased service provider plan.

All of the HP Elite products come with HP enterprise-class security, manageability and Premium 24-hour-a-day, 7-day-a-week, 365-day-a-year support. HP is accelerating the pace of innovation in its AIO systems as it moves to grab the top market-share spot in the U.S. from rival Lenovo, said Derek Everett, director of desktop product management for HP. "With the EliteOne, we have reduced thickness, better design, pinpoint finger touch for Windows 8, NFC, fast-charging USB," he said. "There is just a lot of innovation that we are packing into those All In Ones. That's what makes it exciting."

Everett said HP is No. 2 in the all-in-one market behind Lenovo, with the computer giant moving aggressively to close the market-share position. "We are doing our best to close that gap," he said.

Everett said the consumer market has already made the move to AIO systems, and that change is now taking hold in the commercial market.

"All In One is the fastest-growing subset of the commercial desktop PC market with 15 to 20 percent growth rates," said Everett. "We have seen that with our own business." He said the market growth is being driven by the broad appeal of the space-saving smaller footprint of the AIO offerings, along with the energy savings provided by AIOs in comparison with older systems or bulkier desktop offerings.

"We are seeing high-profile deployments where people are really looking for a stylish, progressive, clutter-free environment," said Everett. "Think of a hotel that has computers for their customers to use. That [AIO system] would be their choice as opposed to towers with a monitor."
